Election Maps

In January 2022, we implemented the approved Colorado Redistricting Commission changes for Boulder County. This resulted in some changes in district numbers and boundaries. The maps available on our website reflect the 2022 redistricting changes.

Precinct active voter counts were also reviewed to ensure the count was not greater than 2,000 as required by statute. This resulted in some precincts being combined and an overall reduction in the number of precincts. Finally, we renumbered the precincts to eliminate gaps in precinct numbers. Learn more about the Redistricting and Reprecincting processes.

This table summarizes the district number changes that occurred.
